So lets say hypothetically there was a 416L doka that has a double clutch, and that truck was leaking pretty good from the rear main seal, as well as the transmission input seal. The clutch has a bit of chatter when attempting to go from a standstill.
Would you bother taking the whole damn thing apart and fixing all the seals in the gearbox and engine, or just keep adding oil?
If you drive on the road, fix it, the 2 wheeled motorcycle riders wouldnt want to go slip sliding away.
If you go through water, the little fishies and other water creatures including the tree huggers would appreciate it.
If you are married, live with your parents and had a beautiful interlock driveway, or had a garage with a cement floor, it wouldnt look ugly or be a health hazard from falling.
To keep filling it would only make the oil companies happy, and richer.
The truck has been driven quite a bit now, and it appears to be getting worse, not better. So, yeah, time to strap on the tipping brackets I suppose. It's more than a little bit of effort to get to the rope seal and trans input.
It's not really that technical, but just laborious, like digging post holes by hand.
What Trevor said is true per my manual and looking at doing just this on my Om352 a few weeks ago.... Seeing as it wasn't leaking I didn't mess with it. I also have the seals in hand and they appear to be 2 parts, and a pain to install.
I have read older threads where some have done the lower seal by pulling just the pan, but I would plan on pulling the motor and what ever is attached as one unit if you can to do the top half as the crank has to be removed.
i pulled apart a trans with dual clutch and cascade from a 406 a few years back and dont recall seeing an input seal. trev can probably confirm looking at the epc.
Just for a laugh i'd try 'oil seal rejuvenator' in the engine oil. it swells the up the seals by 5% and lasts as long as the oil is in the engine. its been used by me very sucessfully on old tractors and Landrovers saving a lot of time and hassle rebuilding engines.
Not my truck, just working on it in my "spare time" (the joke is I have no spare time)
